  29  * @name: a unique symbol name for this feature
  30  *

  33  * any version.

  38  * @gles_availability: flags to specify which versions of GLES the
  39  * functions are available in. Should be a combination of
  40  * COGL_EXT_IN_GLES and COGL_EXT_IN_GLES2.

  42  * @extension_suffixes: A zero-separated list of suffixes in a
  43  * string. These are appended to the extension name to get a complete
  44  * extension name to try. The suffix is also appended to all of the

  46  * an alternate suffix for the function names.

  48  * @extension_names: A list of extension names to try. If any of these
